QfiPEGIFIOATION forming part of Letters Patent No. 658,758, dated October 2, 1900. Application filed November 9, 1899. Serial No. 736,375. (No model.)

2'0 aZZ whom it may concern: Be it known that we, WILSON WORTH BUR- SON, residing at Rockford, in the county of Winnebago, and WILLIAM WORTH BURSON, 5 residing at Chicago, in the county of Cook, State of Illinois, citizens of the United States, have invented certain new and useful Improvements in Steam-Engines, of which the following is a specification.

[ Our invention relates to certain improvements in engines which are provided with a revolving piston; and the objects of our improvements are, first, to provide an engine with a piston extending radially outward I from its supporting-shaft, a cylinder provided with two inwardly-inclined conic heads and a bisecting groove inclined to the piston-shaft, a disk provided with an opening for the piston and its supporting-shaft held in the guide-grooveof the cylinder tangent to the conic heads on oppositesides and adapted to move with the piston; second, to provide an engine with a piston extending radially outward from its supporting-shaft, a cylinder provided with a bisecting guidegroove inclined to the piston-shaft, a disk moving in said guide-groove provided with an opening for the piston, and packing-pieces between the disk and piston, and third, to 0 provide an engine having a piston extending radially outward from its supporting-shaft, with a coacting cylinder having a guidegroove inclined to the piston-shaft, a disk movingin said groove held against the steam- 5 pressure by antifriction devices and moved by the piston in its rotation. We attain these objects by the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 is a perspective view of the engine. Fig. 2 is a longitudinal vertical section of Fig. 1. Fig. 3 shows the A end of the engine divided on the plane of the disk D, the disk being in place. Fig.4shows the A end of the cylinder, the complement of Fig. 3. Fig. 5 is a longitudinal section of Fig. 3 with the disk removed. Fig. 6 shows piston 0, disk D, and shaft 0 in relative positions. Fig. '7 is a longitudinal section of Fig. 4. Fig. 8'is an end view 'of piston C and connecting parts. Fig. 9 is an edge view of piston O and packing-pieces O 0 Similar letters refer to similar parts throughout the several views.

The conic cylinder-heads A A and the obliquely-divided cylinder 13 B constitute the engine-cylinder. The shaft 0, passing centrally through the cylinder, has the piston O fastened radially to it. The disk D divides the cylinder obliquely in two parts, the opposite alternating sides being tangent to the conic cylinder-heads. The part of shaft 0 which passes through disk D is preferably enlarged and rounded into a ball shape and the disk hollowed to fit the same, Figs. 6 and 9. The disk is slotted to permit the passage of the piston through it and is turned by the piston in its revolution in the cylinder. The disk is tangent to the conic cylinder-heads A A on its opposite sides, and at the point of contact the heads may be flat-teped somewhat the better to permit packing when desired.

. It is readily seen that the piston is perpendicular to the disk at each of its tangent points of the conic heads and inclined to it at all other points of the circle, and hence it is seen that an opening in the said disk which would fit the piston at these tangent points would not permit it to pass through its inclined points. To provide for this relative 8o movement of the piston and disk, we prefer to make the ball in three parts, the central part being the thickness of the piston and preferably homogeneous with it and shaft 0. Then two segments are made, completing the ball, and are pivoted to the central part by pin .0 which enters a hole in disk D, Fig. 9. .The

piston-slotin disk D is made to fit the rounded pieces 0 O and hence permits the inclined contact of the said piston and disk in their 0 rotation, Fig. 8. The piston is packed in its contact with the cylinder, as is also the disk,

by the packing d, placed in suitable recesses and held in contact by the springs d or in any other manner desired. The friction of the disk may be relieved by the ant-ifrictionballs I) I), placed in suitable grooves b b.

To secure economic working of the engine, suitable cut-off devices may be used, but we have not thought it necessary to showsuch IOO means here.

In operation in the form here shown the steam is brought by the pipe E from the boiler, which pipe branches into pipes E and E and conducts the steam to inlet-ports on opposite sides of disk D and into opposite ends of the cylinder. An exhaust-portis preferably made in the end of the cylinder, close to the tangent point of the disk therewith, as the piston approaches said tanget point, and

the inlet-port is placed on the opposite side of said tangent point, which serves as an abuthaust-ports and using the opposite or inletports for the exhaust.

Since the disk bisects the cylinder obliquely, it is seen that substantially thesame pressure is exerted upon the piston during its entire circuit of the cylinder, as atthe tangent points of the disk and conic heads the entire piston is on one side of the disk, and between these tangent points the piston has an exposure to pressure upon both sides of the disk, the thickness of the latter being at all times upon the piston-surface.

\Ve have described our engine as adapted to the use of steam, but it may be used with gas or any other suitable motive power, and can be used as a force-pump.

Various modifications can be made in the above-described mechanism without departing from the scope of our invention.

What we claim, and desire to secure by Letters Patent, is-

l. The combination of a cylinder with two inwardly-inclined conic heads and a bisecting guide-groove inclined to opposite sides of the conic heads, a piston extending outward from its supporting-shaft adapted to rotate in said cylinder, a disk provided with an opening for said piston and held in the guide groove tangent to the conic heads to form abutments on opposite sides of said disk, a packing-piece in the disk-opening -on each side of the piston, adapted to move with the disk and slide upon the piston sides, with inlet and exhaust ports, operating substantially as set forth.

2. The combination of a cylinder provided with two inwardly-inclined conic heads and a guide-groove bisecting said cylinder on a plane tangent to opposite sides of said cone,

a piston extending radially out-ward from its supporting-shaft, a disk provided with an opening with concave edges for the pistonand held in the guide-groove tangent to the conic heads, packing-piece fitted to the opening of the disk and held against the piston, the inner end held at the radial center of the piston and the outer held in the disk guidegroove, whereby a steam tight union is formed between the disk and piston in their rotation, and inlet and exhaust ports, operating substantially as set forth.

It is readily understood that and formed with a ballfitting connection therewith moving in the guide-groove tangent to the conic heads, a packing-piece with convex side fitting the disk-opening and flat side next to the piston, the inner end of said apiece held at the radial center of the piston and the outer end moving in the guide-groove with the disk,operatingsubstantially asspeci tied.

at. The combination of a cylinder, a piston formed with a ball-shaped connection with its shaft, said ball made with a central part and two segment-pieces pivoted together, and pieces extending outward alongside of the piston, a disk fitted to said central ball and side pieces, whereby the said piston and disk may rotate together, substantially as specified.

5. The combination of a cylinder, a piston with a ball-shaped connection with its shaft, said ball made with a central part and two segment-pieces pivoted together, said segment pieces connected 'to two cylindrical pieces extending outward along the faces of the piston, a disk fitted to said ball and cylindrical pieces, whereby said piston and disk shall rot-ate together by the action of the steam, substantially as described.

6. The combination of a cylinder, a piston with a ball-shaped connection to its supporting-shaft, said ball made with a central part and two segment-pieces pivoted together, said segment pieces joined to two cylindrical pieces extending outward along the faces of the piston, the outer ends connected by a tiepiece extending across the end of the piston, a disk fitted to said ball and cylindrical pieces, operating substantially as set forth.

7. The combination of a cylinder provided with two in wardly-inclined conic heads, a piston extending outward from its supportingshaft adapted to rotate in the cylinder, a disk provided with an opening for said piston and formed with a ball-fitting connection therewith, a packing-piece on each side of the piston in the disk-opening, inlet and exhaust ports near the abntments and'antifriction devices placed in the guide-groove adapted to resist the side pressure of thes'team upon the disk, operating substantially as specified.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
